Overview
The LTM8003IY-3.3#PBF is a high-performance, 40VIN, 3.5A continuous step-down Silent Switcher µModule regulator produced by Analog Devices Inc. This power module integrates the switching controller, power switches, inductor, and all necessary support components into a single package. It is designed to minimize EMI while delivering high efficiency at frequencies up to 3MHz. The module operates over a wide input voltage range of 3.4V to 40V and supports an output voltage range of 0.97V to 18V. Its compact, thermally enhanced BGA package makes it suitable for high-density point-of-load regulation and automated assembly by standard surface mount equipment.
